Ok, I'm no expert but here are a few things:
-do not put code tags in spoiler tags, it makes it kinda unreadable
-you're ship is kinda slow for ion tech. In the component summary at the class design tab you can see how much tonnage your engines use. Most people seem to have that at 25-50%.
-your Est Time is higher than your range. This useless unless you intend to use a fuel tanker. So make more fuel tanks (or whatever they are called) or remove some engineering spaces for some more sensors.
-you have an active sensor on your ship. Active sensors are afaik only used to detect ships (based on weight) so your fire control can lock on them. Useless for your ship, unless you do it for roleplay purposes. If you want to detect enemies with it, you can better et a thermal sensors. They are passive (EM sensors can detect active sensors) and have a better range. They cannot be used to spot enemies for your fire control though, and they see enemies based on thermal signature (engines)
-I always make specialized geo surveyships and grav surveyships, although other people might combine them, like you do. Geo sensors are commercial and grav sensors are military. So if you have a geo ship with commercial engines and no grav sensors it will be a commercial engine and will not need maintenance (except if it gets shot ofc
)
btw: you will run out of minerals on earth very quickly, so you probably want to create a lot of auto mines and bring them to planets that have duranium (used for everything) and the other mineral that is needed for mines. You bring them there with a freighter. also bring a mass driver there and have one on earth so you can send minerals from the mining colony to earth. You'll need to geosurvey a planet first. Mass drivers and automines are made from the industry tab in the population screen. Try to convert your mines at earth to auto mines too. Except if Mars has some good minerals, cause you might want to get an inhabited colony there than.
Keep in mind that I am a total noob in this game
EDIT:
I have a Jump Gate in the sol sytem!? What the hell, who build that? It's useful though, time to explooore!
